1 Claim.

This invention relates to improvements in metal weatherstrips for metal windows. The object of the invention is to provide an improved metal Weatherstrip which may be easily manufactored and installed or attached to metal windows. Particularly one object of the invention is to provide a metal Weatherstrip in the form of a channel adapted to fit within the channeled members of the metal window sash and operated automatically to function as a Weatherstrip.

Accordingly the invention is embodied in a metal window having its sashes constructed of channeled frame member in combination with channeled metal weatherstrips adapted to fit within the channels of the sash together with means for pressing the Weatherstrip members outward against the window frame. In the accorhpanying drawing illustrating the invention Fig. 1 is a vertical sectional View through the metal window equipped with the improved Weatherstrip, parts are broken away and parts are omitted.

Fig. 2 is a fragmentary sectional view on the line 22 of Fig. 1.

the two window sashes taken on the line marked 3 in Fig. 1.

Fig. 4 is an inside view of the window showing the sash members and the weatherstrips in out- The window casing is generally indicated in Figs. 1 and 2 by the lower sill member 10, the top member H and the side members l2. The members are shown in general sectional outline. The top and side members are formed with channeled recesses marked [4 within which the window sash members slide and which are engaged by the weatherstrips. At the bottom the sill member in has a stepped portion 15 to be engaged by the Weatherstrip.

The upper window sash is formed of the usual four members ll which enclose the window pane IS. The lower member I! forms an inwardly projecting trough E9. The lower window sash is formed of the usual four member 20 which enclose the window pane 2|. The upper member 20 is formed with an overhang portion 22 which hooks into the trough I9 in the usual manner. Each sash frame member I! and 28 is formed with an outwardly facing channel 25. In the overhang 22 one side of the channel 25 is formed by a separate member 25.

There are three weatherstrips for the upper window. They are marked 21, 28 and 29 in Fig. 3 is a horizontal sectional view through Fig. 4. There are four weatherstrips for the lower window and they are marked 30, 3|, 32 and 33 in Fig. 4. Each Weatherstrip is in the form of an outwardly facing channel having the two channel wing portions or members 35, 35

which are joined by the bridge member 36, see.

The bullet spaced suitable distances apart so that the Weatherstrip will be under even pressure throughout its length as will be understood.

The weatherstrips are held within the sash frames by studs 45 or by screws as at 46 in Fig. 2. The studs have washers 51 or like means which prevent the weatherstrips from being pressed too far out of the sash channels. Thus when the upper window is lowered the studs 45 in the top member I! prevents the top weatherstrip from moving too far upward out of the top, and the screws 46 prevent the middle weatherstrip from being pressed too far downward from the lower sash. The studs in the side frames hold the strips in position before installation.

The weatherstrips according to this invention are easily cut off in suitable lengths from long strips or lengths formed by machinery in the proper cross sectional dimensions. The bullet catches and holding studs or screws are inserted from the outside and require but little work.

We claim:

In a window structure, a metal window frame comprising a top, two sides and a sill, said top and sides having inwardly facing grooves, an upper and a lower metal window sash having longitudinal grooves facing and sliding within said frame side grooves, said upper window sash having an upwardly facing groove adapted to engage within an inwardly facing groove in said frame top, when the window is closed, weatherstrips in said sash grooves, said sashes having overlapping portions formed with grooves facing each other in overlapping relation, the groove in the lower sash fitting over the groove in the upper sash, a separate member in the overlapping groove in the lower sash to form a weather- 10 the weatherstrips therein to move the same outward into weathertight relation with the bottom of the corresponding frame grooves and away from the bottoms of said Weatherstrip grooves, the bottom Weatherstrip being moved into weathertight relation with the window sill when the window is closed and means in the sashes for limiting said outward movements of said weatherstrips.
